"Today's Supreme Court decision upholding the Cross State Air Pollution Rule will lead to cleaner air in New York. Our strategies to reduce emissions from power plants, factories, vehicles and other sources over the past decade have led to cleaner air across New York State. Yet pollution continues to blow in from out-of-state sources. Today's decision will require polluting upwind sources to do their share, providing New Yorkers with cleaner, healthier air and helping to level the playing field for New York businesses."
